A coil can be wound around the outer periphery of the insulation layer for connecting multiple reactance elements and reactance filter converters. The coils may relatively increase the wire diameter of the reactance elements corresponding to the operational voltage of the reactance elements and the power factor adjusted by the filter converters so as to be installed in the main body with corresponding volume, enabling temperature reduction and cooling via the low calorific structures of the reactance elements and the increase of contact area with surrounding air, and eliminating the need of using insulation oil in the main bodies.

Description

Dry saver

The invention relates to a dry power saver, in particular to the inside of the power saver body without using insulating oil for cooling and cooling.

According to the regulations, the power saver is mainly used in the process of power conversion, and the power used will be improved, and the power can be fully utilized and excess power can be eliminated. In the process of eliminating excess power, such power saver absorbs the reactive power through the reactance, limits the overvoltage in the access point, and uses filtering to improve the current waveform and eliminate various clutter and harmonics during the power transmission process to eliminate the The required electromagnetic induction allows the load to fully use clean and high-quality power to save power costs and extend the life of the equipment.

However, in the circuit structure using the reactive filter, such a power saver sometimes has to adjust the multi-section switch of the energy-saving component according to different interference environments to control different power factors, but in this operation process and the reactance component factor, Electronic circuits are prone to heat generation effects of circuit structures and must be cooled.

Taking the self-cooling energy-saving device of Taiwan's new patent No. 101212340 as an example, as shown in Figures 1 and 2, the power-saving body 10 shown is provided with a plurality of different heights of the conduit 11 and two or two.

In addition to filling the inside of the plurality of conduits 11 to cool the heat sink 12, the control region of the body 10 needs to be provided with accessories related to the insulating oil 13 in addition to the switching unit 17, such as Oil drain valve 18 and oil level gauge 19. The "self-cooling energy saver" can achieve the heat dissipation and maintain the working efficiency of the energy-saving circuit through the foregoing structure.

However, the use of insulating oil 13 in such a power saver, in addition to having to monitor the amount of oil and normal operation through the oil level gauge 19, is more troublesome, the insulating oil 13 disposed inside the power saver will absorb oxygen in the air for a long time. Oil and scale are generated by the moisture, and the insulating oil 13 is liable to increase the water content in the oil due to the generation of the oil stain and the penetration of the moisture, and the performance of the power saver is gradually deteriorated.
